y and use my invention,l will `proceed to describe its constructionand op eration`.- i

l v A represents the frame ofthe machine of (rectangular form, and` `constructed `in the usual j manner.

1B represents an i endless"` apron! which `works over drums orxrollers jC, 1),.one` C,

l at "the front and the other D, at the back fend ofthe frameA, as shown in Fig;

E, is arollerat the back end of the `frame =A,` and Fis a roller at the front end vdirectly over the roller C, andifGfis a roller` at `the upper end of uprights *(a) I (a) at the front end.V of the framejAJAroundthe three rollers E, ,(F, Grycordsvor strings (Zn) pass, portionsof which between the -two rollers E, "Fi, are in contactfwth the endless apron j( B, asclearly shown inFig.` 2.

e H, Fig. 2is a shaft,]`at the lower part of the frame Asaid shaft having pulleys I, J, i

l `upon it. `A; belt (b) passes around' the pulley I, and one end of the roller C, and a e. belt (c) passes aroundfthe pulleyv .Land a pulley K on adrum lL,over which the end- `less apron B, passes, see Figs. 1` and 2.

C, see Figs. land 2, i j i N1 1s a shaft on the upper part "of the frameA, said shaftlhasa pulley O at one iend, which `pulley rests orjbears upon the `pulley.M, seeFig. 4. VThe pulley @,has a Y f e e e 'recess (e) cut itsedgeforperiphery said san`1e`,"`referencej` being "hadf'to the annexed y drawings,` j niaking"` apa recess being of curved form` andcorrespondl ingmversely tol` a segment? of the pulley M: On the shaft N, directly over the endless apronlB, there is, a `pulley D', which has` a pendent (f) attached to it,`,see Figs. Vl and` 2, and adjoining the pulleyO, on ther same joining e dotted lines in Figs. 2 and 4."

(la) and the hub or boss (j) passes through the hub or boss (z') of the loose pulley and has va disk (la) `screwed to it, see Fig. 3.

yThe outer edge ofthe hub or boss (i) passes into a collar (Z) which encompasses the hub orboss (j) and a spiral spring (m) is placed around the collar (Z) within the hub or boss (i). S, is a spring catch which passes into Jthe collar (Z) and through the hub or boss (i), a hole being made in the collar and hub `or boss (i) to receive the spring catch, see `Figs.' 3 and 4.

T, Figsfl, 2 and 4, is a lever having its fulcrum at (n) on the frame A.. The outer end of the lever T rests or hears upon the perlphery of the cam Q, as shown clearly in Figs. 2 and 4.

U is a" lever having its fulcrum at (79),

`the inner end of this lever rests upon a projection (r) on the side of the loose. pulley R,

see Fig. 4. The loose/ pulley R is provided with projections V, V, on its periphery.`

W'v isthe .pen beam to which the pens X are attached, the lower ends of the pens rest upon the endless apron B. The pen beam worksloosely in bearings (s) (s)` on` the frame A. j

The hubs or bosses (i) (j), collar (Z) `and spring (m) form `a spring friction clutch and conneot at the proper time, the loose passes aroundl'theipulley Mand` the ishaft N, there isa cam Q, see jFig. `l, and dotted lines in Figs. 2 and 4. Thereis also" fa stop' (g) attached 'to the shaft N, and ad? hecamQ. This stopis shownby y loathe fendof theehaft (a) of rheuma L`,`-`there are two pulleys "K, R."^The"pulley pulley R with the fast pulley K as will pres.t ently be shown.

Operation: Power being applied to the rollers C, the endless apron B, is moved over the rollers C, L, D, and the sheets of paper (a) are fed in between the apron B, and the cords (o). The front edges of the sheets strike the pendent (f) and rotate the shaft N, a trifle so as to throw the recess (e) in the pulley oft' of the pulley M and as the perpheries of the two pulleys are then in contact the shaft N rotates and the prominent parts of the cam Q raises the lever T and the lever T in raising throws the spring catch S up out of the collar (Z) and hub or boss (i), and the spring (m) consequently 'forces the loose pulley R againstthe fast pulley K sufficiently tight to cause the loose pulley to rotate and the projections V, V, on the loose pulley, tilt or raise the pen beam lV and the pens are raised from the paper. The projections V may be of any length and placed on the pulley at proper points so as to act properly or at the desired time upon the pen beam. The pulley R may make one revolution during the passage of each sheet of paper underneath the pens and the pulley O, also makes one revolution in the `same time, the recess (e) fitting over the pulley M and preventing any casual movement of the vshaft N. The stop (g) and lever U, serve to stop the motion of the shaft N at the termination of every revolution.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,

Lifting the pens X, from the sheets of paper (a') at the proper intervals by means of the mechanism herein shown and described, viz: havingr the front edges of the sheets (a), as they move along on the endless apron B, strike against a pendant (f) attaehed to a pulley D', on a transverse shaft N, on the frame A, said shaft being provided with a pulley O at one end having a recess or groove (e), cut in its periphery and a cam Q, the pulley O, Working on bearings on a pulley M, underneath it, said pulley M, being driven by a belt (ai) from the driving shaft C. The cam Q, operating a lever T, by which the spring clutch is allowed to'aet and connect the pulleys K', R, at one end of the drum L, the projections V, on the lower pulley R, raising the pen stock s0 as t0 leave the blanks or spaces at the clesired parts of vthe sheets, as herein set forth.
